Product Details
The CHINT 100A 4 Pole 100mA Type A Time Delayed RCD (SKU NL1‑100‑4100/100‑S) is a robust residual current device designed to protect electrical systems from earth leakage faults while providing discrimination in multi‑RCD installations. It features a 100 ampere current rating and 100mA tripping sensitivity, making it ideal as an upstream protective device in three‑phase distribution boards, workshops, commercial installations, and larger domestic panels where selective coordination is required.
Built to meet recognised safety standards, this RCD incorporates a time delayed Type A characteristic that helps prevent nuisance trips from transient currents and ensures downstream devices operate first on fault conditions. The four pole design provides complete protection for all lines in three‑phase circuits plus neutral, giving full circuit security.
CHINT’s NL1 series RCDs are valued for their strong build quality and reliable performance. The device is DIN‑rail mountable for quick and secure installation into standard enclosures. With a compact profile and consistent performance, this RCD is a dependable choice for electrical professionals and DIY installers looking for a cost‑effective solution that does not compromise on safety.
Whether upgrading an existing panel or building a new distribution setup, this time delayed residual current device provides essential protection against earth faults and supports compliance with modern electrical safety requirements.
